(Solved) Bluetooth is on, but unable to detect any devices

Yes, lol. It's almost 11pm here... Second time in one thread I did not notice a detail.

no worries. Thank you for helping. should i change both file names? cause its returning a command not found error

Ok I just downloaded the file to be sure:

sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd

You may need to run it from your Downloads folder. Open terminal, then Change Directory to Downloads

cd ~/Downloads

Then

sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd

sudo modprobe -r btusb

sudo modprobe btus

lee@lee-HP:~/Downloads$ sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd
lee@lee-HP:~/Downloads$ sudo modprobe -r btusb
lee@lee-HP:~/Downloads$ sudo modprobe btus
modprobe: FATAL: Module btus not found in directory /lib/modules/5.4.0-80-generic
lee@lee-HP:~/Downloads$

Can you run

sudo depmod

then try to modprobe btus again?

still got that error :frowning:

lee@lee-HP:~/Downloads$ sudo depmod
lee@lee-HP:~/Downloads$ sudo modprobe btus
modprobe: FATAL: Module btus not found in directory /lib/modules/5.4.0-80-generic

That is strange... I am running Zorin 16 with Kernel 5.11 and it shows up in my system.
Try:

sudo apt-get install -y linux-modules-extra-5.4.0-80-generic

Relay the output and if successful, log out and in, test Bluetooth...

i am running 15.3 if that matters

lee@lee-HP:~/Downloads$ sudo apt-get install -y linux-modules-extra-5.4.0-80-generic

should i still do this again?

Nah... If it's working, it's working. Not sure why the modprode error, but... Why question fate (unless you don't like the fate dealt)?
